Five-bar linkage ABCD, consisting of links 1, 2 and 3 and slider 4, has two degrees of freedom. Slider 4 moves along fixed guides x-x. Links 5 and 6 are connected by a screw pair. Distance A͞C can be varied by setting link 6 in the required position with respect to link 5. When link 6 is connected by turning pair C to link 2, five-bar linkage ABCD is converted into slider-crank linkage ACD having only one degree of freedom.
